Systems Requirements |
To record this tutorial, we will use-
|
| Show Slide:
Pre-requisites |
To practice this tutorial, basic knowledge of analog and digital electronics is required. |
| System Computer:
Desktop icon |
To launch eSim, double-click on the eSim icon on your desktop. |
| System Computer:
eSim startup window |
The eSim window opens up. |
| eSim Main Window:
Creating device model library |
Now let us create a device model library for a Diode. |
| eSim Main Window:
Click on >> Model Editor button |
Click on the Model Editor button on the left tool-bar. |
| Model Editor Window:
Click >> New and Enter Model Name >> diode_test>>Click on OK |
Click on New and type the Model name as Diode underscore test.
Click on OK. |
| Model Editor Window:
Select >> Diode category |
Now select Diode category. |
| Highlight | The basic parameters of a Diode is displayed.
|
| Model Editor Window:
Click >> Save
|
Click on the Save button at the top of the Model editor window.
|
| Let us run our Diode model using an example. | |
| eSim Main Window:
Open >> Diode_Characteristics |
Open the Diode_characteristic example from the Examples folder.
Examples folder is located in eSim hyphen 1.1.2 folder which you have downloaded while installing. |
| Double Click >> Diode_characteristic in projects | From Projects, double-click on the Diode_characteristics example. |
| eSim Main Window:
Click on>> Open Schematic |
Open the schematic and view the circuit.
|
| eSim Main Window:
Click on >> Convert Kicad to Ngspice |
Click on Convert Kicad to Ngspice button on the left tool-bar. |
| Click >>Analysis tab
Click >> Source Details tab. |
Don’t change the previous values in the Analysis and the Source Details tab. |
| Kicad to Ngspice window:
Click >> Device Modeling tab and Click >> Add |
Next, click on Device Modeling tab.
And then click on Add button at the right of the text box.
|
| Device Modelling tab:
Select >> Diode folder >> diode_test |
Select the diode underscore test from the Diode folder. |
| Click on >> Convert and click >> OK | Click on Convert button at the bottom of the window.
|
| Kicad to Ngspice window:
Close >> Kicad to Ngspice window |
After this, close the Kicad to Ngspice window. |
| eSim Main Window:
Click on >> Simulation Button |
Click on the Simulation button on the left tool-bar and check the output. |
| Python Plotting Window:
Check OUT nodes >> click plot |
Check the OUT node and click on the plot button. |
| Let us now edit our Device model to re-check the output. | |
| eSim Main Window:
Click on >> Model Editor button |
Click Model Editor button on the left tool-bar. |
| Model Editor Window:
Click Edit >> Diode folder >> diode_test |
Click on Edit button at the top of the Model editor window.
|
| Model Editor Window:
point to >> Add/Remove button |
We can add and remove parameters in the model.
|
| Now we will modify the parameters values, to check the effect on the model. | |
| Model Editor Window:
Double click >> value of “N” parameter |
Double-click on the value of “N” and change the value from 1 point 6 7 9 to 4 point 6 7 9. |
| Model Editor Window:
Click >>Save Close>> model editor window |
Click on the Save button at the top of the Model editor window.
|
| eSim Main Window:
Click on >> Convert Kicad to Ngspice button >> click Device Modelling tab |
Now click on Convert Kicad to Ngspice button on the left tool-bar.
|
| Device Modelling tab:
Add >> Diode>> diode_test |
Add our modified Diode underscore test from Diode folder |
| Kicad to Ngspice window:
Click on >> Convert
|
Click on Convert button at the bottom of the window.
|
| eSim Main Window:
Click on >> Simulation Button |
Now, click on Simulation button from the left tool-bar and check the modified output. |
| Ngspice Plot Windows:
Hover cursor over the ngspice plot |
Notice the change in the output plot. |
| Let us now upload an external model file in eSim. | |
| eSim Main Window:
Click on >> Model Editor button |
Click on Model Editor button on the left tool-bar. |
| Model Editor Window:
Click on >> Upload |
Click on Upload button at the top of the Model editor window. |
| Model Editor Window:
Diode folder >> D.lib Note: We are uploading D.lib from Diode folder for demonstration, user can upload any .lib file from his system. |
Go to Diode folder and select D dot lib from it
Note: We are uploading D dot l i b from Diode folder for demonstration.
|
| Model Editor Dialog box:
Type D1 >> click OK |
A dialog box opens where we will enter the Model name as D1.
|
| Model Editor Window:
Close >> model editor |
Now close the model editor window. |
| eSim Main Window:
Click on >> Convert Kicad to Ngspice button >> click Device Modelling tab |
Click on Convert Kicad to Ngspice button on the left tool-bar.
|
| Device Modelling tab:
Click on the Add button >> User Libraries folder >> D1 folder |
Add our modified D1 from User Libraries folder. |
| Kicad to Ngspice window:
Click on >> Convert and
|
Click on the Convert button at the bottom of the window.
|
| eSim Main Window:
Click on >> Simulation Button |
Lastly, click on the Simulation button from the left tool-bar and check the modified output. |
| <<PAUSE>>
